Daily nutrient coverage with a boost for male performance

Blackstone Labs MULTI is a men's multivitamin that mixes basic nutrient coverage with some hormone support. The idea is straightforward. It gives you a wide range of vitamins and minerals at doses higher than basic needs in spots like B vitamins, vitamin C, zinc, and magnesium. Then it adds plant extracts linked to male energy, like Tribulus terrestris and Fenugreek 50% extract, to stand out from a regular store multi. This isn't a pre-workout or a full testosterone booster. It's your daily nutrient foundation with a guy-focused twist.

The vitamin and mineral core is the best part. Thiamine (Vitamin B1) at 18mg is right at the high end of the 5-18mg range for real metabolic help. Thiamine turns into thiamine pyrophosphate, which helps your body process carbs, run the Krebs cycle, and make ATP. Basically, it means better energy from your meals, especially if you're active and eating more carbs around workouts. Riboflavin at 18mg and niacinamide at 50mg back that up for energy in your cells and making NAD+, without the skin flush from other niacin forms.

Vitamin B6 at 18mg, B12 at 250mcg, pantothenic acid at 50mg, and biotin at 300mcg keep the metabolic support going. B12 is high, but it's the cyanocobalamin form, not the fancier methylated one. Biotin is standard for a multi, not a mega dose for hair or nails. Vitamin C at 250mg gives solid antioxidant and immune backup, while vitamin A from beta-carotene, vitamin E, vitamin K, and vitamin D3 handle basics for immunity, tissues, and bones.

For minerals, magnesium is 200mg from magnesium aspartate and magnesium oxide. The dose is solid, but the forms are a mix: aspartate is

Key Highlights

  • 18mg Thiamine (Vitamin B1) — this nails the top of the 5-18mg range for real metabolic kick. It helps turn carbs into ATP, so you feel that energy from food better, especially if you're training hard.
  • 18mg Riboflavin plus 50mg Niacinamide — a solid B-vitamin combo for cranking out energy in your cells. They build coenzymes that handle oxidation and give you real cellular fuel without any stim buzz.
  • 18mg Vitamin B6, 250mcg B12, and 50mg Pantothenic Acid — this is a beefed-up B-complex for a daily multi. It helps with nerves, blood cells, protein breakdown, and handling the energy needs from workouts and dieting.
  • 250mg Vitamin C — way above the bare minimum, and it really helps with antioxidants and keeping your immune system strong. For gym folks, it's like extra protection without needing another bottle.
  • 1,000 IU Vitamin D3 — a good everyday dose in a form your body uses well. It supports bones, immunity, and the hormone basics that active guys look for in a men's multi.
  • 200mg Magnesium — super relevant for active people since it’s in tons of reactions for muscles, energy, and recovery. Solid inclusion, but mixing magnesium oxide with aspartate makes it practical, not top-shelf.
  • 18mg Zinc — a strong dose for immunity, enzymes, and hormone support. Zinc's a go-to in men's formulas, and this is way better than the weak amounts in basic multis.
  • 90mcg Iodine plus 45mcg Selenium — a smart duo for thyroid help. Iodine builds thyroid hormones, and selenium handles the enzymes that manage them.

Who Is This For?

  • Guys doing steady hypertrophy or bodybuilding workouts who want nutrient backup with a male vitality kick. High B vitamins, vitamin D3, zinc, magnesium, Tribulus, and fenugreek make it fit active dudes better than a cheap multi.
  • Busy workers training 3-5 times a week with up-and-down food quality. Gives broad coverage in one serving, strong on B-complex for energy and zinc-magnesium for recovery and hormones.
  • Lifters cutting calories where meals get boring. Vitamins and minerals plug gaps from dieting, plus herbs add more than basic support.
  • Men over 30 not chasing heavy hormone stacks but wanting daily help for test, thyroid, and recovery. Vitamin D3, zinc, magnesium, iodine, and selenium hit those spots, even if it's not a full booster.
  • Folks who hate powders and like easy tablets that travel. Three tabs beat separate magnesium, zinc, vitamin D, and herb bottles.
  • Rec athletes wanting steady nutrition over stim highs. Not a feel-it-now thing; it's for long-term energy, immunity, and nutrient levels.

How to Use

Take 3 tablets daily, best with breakfast or lunch. Food helps absorb fat-soluble vitamins A, D, E, and K, and makes minerals easier on the gut. If three at once is tough, do two with one meal and one with another. Stim-free, so no workout timing or cycling needed. Use it daily, rest days included, since nutrients and herbs work best steady. Pairs well with protein, creatine, omegas, and pre-workouts. If you're on another multi or ZMA, check overlaps first. Keep it cool and dry with the lid tight for fresh tablets.

What to Expect

First 0-30 minutes: With food, you won't feel a thing right away—that's normal for a no-stim multi. It's built for ongoing support, not instant vibes. Days 1-7: You're just getting steady nutrients, especially if your diet skipped stuff before. Some notice better routine and feeling covered, but nothing huge yet. Weeks 2-4: Here's where it shines, with vitamin D3, zinc, magnesium, iodine, selenium, and B vitamins building wellness, energy, and recovery. The herbs are a slow build too. If you want quick feels, look elsewhere; this is for compounding benefits through daily use.

Frequently Asked Questions

What exactly is Blackstone Labs MULTI?

Blackstone Labs MULTI is a men’s multivitamin built on essential vitamins and minerals, with added male-performance herbs including Tribulus terrestris extract and fenugreek extract. It is designed more as a daily nutritional foundation with a testosterone-support angle than as a standalone hardcore hormone product.

How many tablets are in each serving?

The validated product context indicates a 3-tablet serving, with 90 tablets per bottle for 30 servings total. That makes it a once-daily multivitamin protocol rather than something you take multiple times per day.

Should I take MULTI with food or on an empty stomach?

Take it with food. This formula contains fat-soluble vitamins A, D, E, and K, and meals generally improve both absorption and stomach comfort when taking a multi that also contains minerals like magnesium and zinc.

Is the magnesium dose meaningful?

Yes, 200mg is a useful daily amount, especially for active users. The caveat is that the formula uses a blend of magnesium aspartate and magnesium oxide, so the amount is solid but the form system is more practical than premium.

Does Blackstone Labs MULTI contain stimulants or caffeine?

No. This is a stimulant-free daily product, so it will not give you a pre-workout rush or interfere with evening training schedules the way a caffeinated formula can.

Is the herbal side fully transparent?

Not completely. The vitamin and mineral doses are disclosed individually, but the male-support botanicals are not all fully broken out by exact dose from the verified panel data available here, so the herb side should be viewed as less transparent than the micronutrient panel.

What are the most meaningful minerals in this formula for active men?

Zinc at 18mg, magnesium at 200mg, iodine at 90mcg, and selenium at 45mcg are the standouts. Zinc and magnesium are commonly discussed for recovery and endocrine support, while iodine and selenium work together in thyroid hormone physiology.

Can I stack MULTI with creatine and protein?

Yes, and that is one of the best ways to use it. Creatine supports phosphocreatine availability for high-intensity performance, protein supports muscle protein synthesis, and MULTI covers the micronutrient side those products do not address.

How long does it take to notice benefits from this product?

This is not an instant-feel supplement. Most of the value comes from consistent use over 2-4 weeks as you maintain steadier intake of key vitamins and minerals, especially if your baseline diet was leaving nutritional gaps.

Is this a replacement for a dedicated testosterone booster?

No. It includes Tribulus and fenugreek for a male-support angle, but the real backbone of the formula is still its multivitamin and mineral profile. If your goal is a full clinical hormone-support stack, this works better as a foundation than as the entire solution.

Outstanding Frother!
Color: Space Gray
Exceptional! This frother is in another league compared to the cheapo push button frothers. The motor is smooth, quiet and powerful. This has an intuitive thumb dial on top that operates smoothly with a wide range of smooth speed adjustment. It’s gentle enough to froth a little bit of milk for a macchiato and powerful enough to scramble 3 eggs. The head is removable for easy cleaning. It’s also rechargeable. I charged this the day I bought it on April first. I use it at least twice a day. It’s September 26th today and I have yet to recharge it and it’s not showing any signs of needing a charge. One minor quibble is that they give you 2 of the same frother heads. They are built so well, that I don’t imagine it ever wearing out. It would have been nice to get a whisk or something different. Not a deal breaker at all though.

Handheld Mixer/Frother Review A Premium Choice That Transforms Morning Coffee I am thoroughly impressed with this handheld mixer and frother. Each morning, I blend cacao and collagen powder into my coffee, and in the past, I always ended up with stubborn lumps using only a spoon or whisk. I had previously purchased a few inexpensive handheld mixers, but they disappointed me both in price and performance, struggling to mix the powders thoroughly—especially at the bottom of the cup. I came close to abandoning handheld mixers altogether, but decided to give it one last try. After reading countless reviews and carefully comparing models, I opted to invest in a higher-end handheld mixer. The anticipation was high—would this mixer truly distinguish itself from the budget options cluttering my kitchen drawer? From the moment I unboxed it, the difference was clear. The mixer felt substantial in my hand, and the build quality reflected thoughtful engineering. While this model cost roughly twice as much as the cheaper alternatives, it proved to be well worth the investment. Initially, I was concerned about the dial at the top, fearing it might be difficult to control. However, I was pleasantly surprised by its intuitive operation. The unit offers a solid feel, plenty of power, and a versatile range of speeds—from a gentle stir perfect for coffee to an impressively fast setting. I had not previously considered using this mixer as a frother, but as a cappuccino enthusiast, I decided to give it a try. I heated both 2% milk and oat milk to take the chill off, then submerged the mixing wand. Allowing the mixer to rise above the milk introduced air and created a rich, creamy foam—an unbelievable result. My homemade cappuccino now tastes like something from a café. The controls are robust, the construction is reliable, and the power is consistent. Cleanup is effortless, requiring only a quick rinse under the tap. The battery life is also noteworthy, lasting through several uses without losing strength. If you are hesitant to spend a bit more on a quality handheld mixer, I wholeheartedly recommend making the investment. This mixer has become an essential part of my morning routine. Excellent product—well done!

Very nearly the perfect frother for all your basic frothing & mixing needs
Color: Black
There are a lot of middle-of-the-road frothers out there. I've been through a few of them in my recent search for something that could mix and froth well, without taking up any more outlets in my basement kitchen. Of the three Maestri frothers I've tried so far, this one wins the race by a nose. Most recently, these Maestri frothers come in basically three versions: A single-speed @ 8000 RPM, a two-speed @8000/5500 RPM, and this stepless variable-speed version. Aside from that, the only real difference in recent version pack-outs is which attachments they come with. Look over the reviews of the single-speed version and you'll find that while it can and does froth well, it starts at a single, high speed and gets there fast. This makes it pretty easy to spin liquid right out of most common cups and mugs. There is a two-speed version, but it's harder to find, only comes in one color (Grape Purple), and while it's much better than the Maestri single-speed, it still has a couple of quirks that make this variable-speed version win out. This mixes and froths whole milk, half-and-half, or heavy whipping cream, or just about anything else very well. Like all frothers, it takes a little time to learn its nuances and nail down the technique, this will definitely get you there. The best feature of this is easily the speed control. Turn the knob to turn it on at a low speed that's great to get things started, then turn the knob to crank up the speed just enough to do what you need, whether that's mixing or frothing. The low starting speed makes it easy to keep things under control without undue spilling, and the max speed is more than enough to make quick work of getting your froth on. There are really only two complaints I have with this stepless, variable speed version: - I'd really like to have a Press On / Release Off button in addition to the Speed Control knob. More than one time have I gone to turn this off, only to spin the knob the wrong way and crank the speed up to ludicrous, sloshing liquid on the counter. Being able to turn it Off just by letting go of the button would be quick and easy. This configuration would allow using a preferred speed right from the start, while still allowing speed to be adjusted on-the-fly when needed. - Give it a bigger battery. It would cost mere pennies to give this a 2000mAH+ instead of a 1200mAH battery, and I can't think of any reasonable downside to that. - Give the motor a little more torque. It's fairly easy for the current motor, at any speed, to get bogged down in a thick protein powder mix, or when pressing the frother or other attachment a bit too hard into the bottom or side of the frothing container. A bit more "oomph" would prevent that. I really like the overall design and features of thes Maestri frothers better than many other, cheaper versions. This variable-speed version is pretty great as it is and probably the one I would recommend over the single- or two-speed, for most people. But I often find myself using two hands -- one to hold it steady, and the other to turn it on and tweak the knob to the desired speed(s) -- for a device that should arguably need only one hand to use. Just a couple of minor tweaks as noted above would make this the overall best frother of its type that I've used.

Hands down, the BEST handheld frother I've ever used!
Color: Black
Hands down, the BEST handheld frother I've ever used! I got the black one, but any color will have the same results. Over the past 12 years or so, I've used so many different handheld frothers and they've ALL fallen short of expectations for quality, longevity, power, features, and usability. I've used everything from cheap, $15 models to $50+ models and everything in-between. Some with fancy attachments for various types of mixing, frothing, beating, whipping, etc. Some with rechargeable batteries, some without. Some AC powered, some with fixed whisks, some with detachable/replaceable whisks, some with stands, etc. NONE have been spectacular. Most broke within 6 months and got tossed. ALL were major disappointments in the end, including the "revered" Zulay models of which I tried several. I finally found this Maestri House branded, variable speed frother with detachable / replaceable whisks and got one to try. I was literally on Cloud Nine the first time I turned it on. Like, WOW! Not only was it FAST on the highest speed, but it was powerful enough to churn right through milk, eggs, cream, etc, without bogging down like many others. This thing makes milk froth like a milkshake and Matcha Lattes like nothing else I've ever experienced. I used to have to sift my Matcha, then whisk it in hot water, then froth milk and then blend them together to make the perfect latte. and if the milk was cold (my preference), pre-whisking in hot water was a must to avoid lumps. However, with THIS frother? I literally pour my milk into a tall tumbler, drop in un-sifted Matcha powder, and spin up the Maestri House frother at first on a medium low speed to get it mixed, then jump straight to the highest speed to really whip that milk and match up. After about 30-45 seconds, I've got the thickest, richest, smoothest, most aerated latte around. And NO LUMPS at all!!! What a time and dish saver! And cleaning? I just run it under hot running water to get the shaft cleaned and then spin it up in a dish with hot running water for a few moments, then spin it on high for a few seconds in the air to dry it off instantly. Now, I'll be honest here, too. The specs say it can go months on a charge, using it for a couple minutes a couple times daily. Well, I guess it could do that and still spin. But I use it FULL SPEED, churning hard for at least a minute a couple times per day. After about 2 weeks, I can start to notice a speed reduction so I just plug it back in on the charger. All things considered, this is still better than all the other handheld frothers I've used over the years. After using the heck out of this thing for the past 7 months, I've even decided to start selling these in our Japanese gift shop. The manufacturer is has been very responsive both in customer support (I called them about an issue I thought I was having, and they called me back with a couple hours even though I didn't leave voicemail when they didn't answer right away) and in reseller support. I have to give these guys an A+ for responsiveness and quick resolution when problems might arise. HIGHLY recommended!!
